Question

If BC is 9 cm and AC is 12 then what is AB?

Answer 1

Answer:

AB = 3

Step-by-step explanation:

9+x=12

X=3

Answer 2

Answer:

15

Step-by-step Not enough info here, but I'm guessing its a Pythagorean triple. A^2 + B^2 = C^2. So, 9^2= 81, and 12^= 144. 81+144= 225. 15^2 is also 225, making the equation true.
